SPRING.

Application led November 26, 1915.

To all whom i may concern Be it known that l, Jason H. JACOB, citizen of the United States `of America, reM siding at Peoria, in the county of Peoria and State oflllinois7 have invented certain new and useful Improvements in Springs, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to springs and has for its object the production of a simple and etlicient vehicle spring which is adapted to keep the body of the vehicle steady, regardless 0f the condition of the road over which the vehicle may be traveling.

Another object of this invention is the production of a simple and efficient spring which will constitute a shock absorber and Will permit the body of the vehicle to remain level under all conditions, whether loaded or unloaded.

Vith these and other objects in view, this invention consists of certain novel combina tions, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanaying drawings Figure 1 is a side elevation of the improved spring. Fig. 2 is a section taken on line 2 2 of Fig. 1. Fig. 3 is a top plan view of the central bar of the spring Fig. Il is a section taken on line 4 4 of Fig. 1. Fig. 5 is a detailed perspective of one of the plunger rods used in connection with the present spring. Fig. 6 is a detailed perspective ol one end of one of the main springs. Fig. 7 is an embodiment of the invention showing the end plates of the spring provided with a coiled tension device for causing the end plates to remain in their normal position under ordinary cirL cumstances. Fig. 8 is a section taken on line 8 8 of Fig. 1. Fig. 9 is a section taken on line 9 9 of Fig. 1. Fig. 10 is a. section taken on line 10 10 of Fig. 1. Fig. 11 is a side elevation of a modication of the arrangement of the spring shown in Fig. 1. Fig 12 is a side elevation of a still further modification of the spring shown in Fig. 1.

Referring to the accompanaving draW- ings by numerals it will be seen that 1 designates the main sleeve which is provided with a plurality of bead portions 2 formed near the ends thereof and an arch bar or brace 3 is adapted to engage the inner bead portions 2 of the sleeve 1, as illustrated in Fig. 1 of the drawings. These. arch bars or Specification of Letters latent.

' braces 3 are secureljT fastened at their ends `portion 9, which shoe portion 9 is provided l by means of the bolts 5 passing through the central bracing har G. .lt will be Seen that these arch bars 3 will constitute an efficient brace for holding the sleeve 1 in its proper position upon the bar 5. This sleeve l is provided with a plurality of apertures 7 formed therein as clearly illustrated in Figs. 1 and 2 of the drawings and a plunger 8 is slidably mounted Within each end of the sleeve l, as illustrated in Fig. 2 of the drawings.

Each plunger 8 is provided with a shoe near each end thereof with protruding flanges l0, which flanges 10 are adapted to engage the loop 11, which loop 11 straddles the. respective springs 12 and 13, as illustrated in Figs. 1 and flaor connecting the plunger rods 8 to the springs 12 and 13. These plunger rods 8 are adapted to reciprocate within the sleeve 1 as will be. clearly un derstood by carefully considering Fig. 2 of the drawings.

Each of the springs 12 and 13 comprises a plurality of layers of spring or resilient strips and the outer ends ol the respective springs 12 and 13 are connected to theend plates 14 and 15, by means of the bolts .16. These plates 'G and 15 are in turn pivotally connected to the outer ends of the bar 6 by means of the bolts 17 so as to have a free swinging movement with respect thereto. The springs 12 and 13 are connected to suitable supports by means of the loops 18 for efficiently connecting the springs to a vehicle or other supporting means.

ln 7 there is shown an embodiment of the invention wherein the plates '1f-l and 95 f5 are pivotally connected by ineens of e. bolt 1T to the bar 6 and a plurality of coiled springs 19 are wound upon the bolt 17 and are adapted to retain the plates 14 and 15 in the position illustrated in 17 1. under normal circumstances.

The operation of the device is as follows: lll/'hen a load is placed within. vehicle be supported by the springs as illustrated. the springs first being in the position shown in Fig. 1. pressure will be brought to bear. The springs 12 and 18 will thereinv cause the plates 141 and 15 to be moved oixtwardly in the direction indicated b v the arrow i Fig. 1 at the same time spreading the sp and 13. The plungers 8 of course. w' moved inwardlywithin the sise-ve or resin Pli l but the sleeve or casing 1 will be firmly held in its proper position With respect to the bar 6 by means of th'e bracing members 3. As soon as pressure is relieved from the spring. the parts will of course assume their normal position.

From the foregoing description it will be seen that a very simple and efficient means has been produced for permitting the springs to be relieved of considerable preS- sure or weight in view of the fact that some of the expanding action will take place by mea-ns of tlieouter ends of the plates 14 and 15 being moved outwardly.

It of course should be understood that the plates 14 and 15 may be removed and longer platessubstituted therefor if so desired, to accommodate'the different weights adapted to be carried by the 'vehicle body, supported upon `the springs illustrated.

It should'be understood that the spring 13 is adapted to be secured to the axle and is always the same distance from the ground, but it should be further understood that if any sudden jolt from the wheels should occur, the spring 13 would have a tendency to move toward the spring 12 thereby causing the outer ends of the plates 14 and 15 to be spread apart and limit the downward movement of the spring 12 with respect to the spring 13. vL'

In Fig. 11 there is shown an embodiment of the invention wherein a primary spring or rod 20 is employed, carrying a toggle armV 21, which toggle arm 21 is pivotally secured to a toggle arm 22. This' toggle arm 22 engages the lower primary spring 23. The toggle arms 22 carried by each end of the primary springs 20 and 23 are connected to link arms 24 and 25 respectively and these link arms 24 and 2 5 are connected to the upper and lower auxiliary springs 26, asv illustrated in Fig. 11. It will be seen that'when pressure is brought'to bear upon the top spring, the inner ends of the arms 21 will be moved downwardly, thereby raising the v lower ends of the arms 21and causing the outer end of the links 24 to be moved outwardly under thepressure Which'is brought to bear upon the spring.

In F ig. 12 thereis shown still another embodiment of the present invention wherein a primary upper spring or rod 27 is employed. connected to an arc-shaped toggle arm 28, the arc-shaped toggle arm 28 being pivotally connected to an arc-shaped toggle arm 29 carried by the lower primary spring 30. Each of the toggle arms 28 and 29 is pivotally connected to a link 31, the links 31 being connected to the outer or auxiliary springs 32 and 33, as illustrated.
